Password
— no default —

You create this password the first time you set up the router. If you never changed it, factory-reset and set a new one.

No default password ships on the RT6600ax. SRM forces you to set the administrator account during setup, so credentials are user-created. Avoid reusing 'admin'/'root' as the username per Synology's own guidance.

Factory reset

Connect by Ethernet, or join WiFi SSID Synology_(Serial) with password 'synology'. Browse to http://router.synology.com (or http://192.168.1.1:8000) and complete the SRM wizard, which prompts you to create your own administrator account. To reset, hold the RESET button ~4 seconds (soft: network/password) or ~10 seconds (full factory reset) until it reboots.
